The driver who killed a car passenger during an Indianapolis road rage incident won't face any charges because the shooting was self-defense, the Marion County prosecutor's office said Friday.

Although that driver fired the bullet that fatally struck 31-year-old Brandy Brock on the east side Tuesday morning, the driver in the vehicle Brock was in was the first person to shoot, according to a probable cause affidavit.

Andrew Holder, 47, is charged with criminal recklessness, a felony, and carrying a handgun without a license, a misdemeanor. Authorities say he fired first in an altercation that quickly escalated.

Holder will not face felony murder charges, the prosecutor’s office said. Certain offenses, such as burglary, drug dealing, robbery or kidnapping, can lead to a felony murder charge against a suspect even if the person is not directly responsible for the death. Criminal recklessness, while a serious felony, doesn't fall under the offenses that would warrant a felony murder charge in this case, according to the Marion County prosecutor's office.

Criminal recklessness is a Level 6 felony that typically carries a potential sentence of six months to 2.5 years in state prison.

Holder remained held in Marion County Jail on Friday, records show.

The shooting began as a disagreement between Holder and the other driver along 38th Street around 11:30 a.m., the affidavit said. Holder told police the car was driving aggressively and purposely braking in front of him.

The other driver, though, told police that he swerved around a sewer cap.

A passenger in that car told police that both drivers were racing and flipping off each other.

When they pulled up to the intersection of East 38th Street and North Arlington Avenue, the other driver said he stopped his vehicle behind Holder's car. Holder then stuck a handgun out of his driver-side window and fired one shot toward the other driver, according to the probable cause affidavit.

When the other driver saw the gun, he said he grabbed his gun from between the gear shift and his seat. He opened his door, he said, and fired one round back as Holder's car drove away.

The bullet entered the car to the right of the trunk's keyhole, continued through the back and front seats and into Brock's back, court documents say.

A bystander, interviewed by an IMPD detective, also said that the first shot came from Holder's car. Then the other driver shot back. Prosecutors on Friday said the driver acted in self-defense.

After Brock was hit, Holder drove to a fire station seeking help for her. She was taken to Eskenazi Hospital, where she was pronounced dead, according to court documents.

Family members told IndyStar that Brock was an east-side resident and a selfless, devoted mother of two daughters, ages 12 and 6. She also cared for her fiance's 16-year-old son as if he were her own, according to her cousin, Cassie Sheroan.

"We are all completely at a loss for words and devastated," said Melissa Brock, Brandy's mother, in a statement to IndyStar. "I pray something good will come from my daughter's senseless and unnecessary death to make things better for someone else."

Brock's funeral is scheduled for Monday at a funeral home in Kentucky, where Brock has family, Sheroan said.
